Not a diamond; this specimen appears to be a rough quartz, quartzite, or other silicate mineral pebble, not a gem-quality diamond.
Not a diamond; this specimen appears to be a rough quartz, quartzite, or other silicate mineral pebble, not a gem-quality diamond. · Irregular raw pebble / rough unpolished form.
Uncut / Raw (Not applicable as a cut gemstone). Cut

Carat
Cannot be accurately determined as a diamond; estimated mass as a mineral specimen is approximately 15-25 carats.
Color
Off-white to pale greenish-grey, typical of common natural quartzites or weathered river stones.
Clarity
Included / Opaque (Not applicable on the diamond grading scale due to non-diamond composition).
Shape
Irregular raw pebble / rough unpolished form.
Overall Assessment
This item is a raw, unpolished silicate pebble (likely quartz or quartzite) rather than a diamond. It has no gemological diamond value and should not be confused with a precious gemstone.
Cut Quality
Uncut / Raw (Not applicable as a cut gemstone).
Brilliance
Poor to none, due to lack of facets and optical properties of diamond.
Fire
None, as dispersion is minimal in standard quartz/rock pebbles compared to diamond.
Scintillation
None.
Proportions
Non-standard proportions; natural rock fragment.
Symmetry
Asymmetrical, natural water-worn or unshaped pebble.
Polish
Unpolished, rough matte texture with natural weathering.
Fluorescence
Unknown / None visible under normal lighting.
Inclusions
Abundant mineral inclusions, fractures, and surface pits typical of common quartz.
Blemishes
Multiple surface abrasions, fractures, and adhering dirt/matrix.
Origin
Alluvial river or surface deposit, likely terrestrial quartz/silicate rock.
Treatment Detection
No enhancements or treatments detected; completely natural untreated rock.
Estimated Value
Nominal or negligible gemstone value; holds value purely as a common mineral specimen or decorative rock.
Certification Estimate
Not eligible for GIA, AGS, or standard diamond grading reports; could be analyzed by a general geological lab.
Investment Potential
None as an investment asset.
Similar Diamonds
None, as this is visually and compositionally distinct from diamond.
Setting Suggestions
Not recommended for fine jewelry settings due to hardness and lack of cut; if used, wire-wrapping in a rustic or artisan setting.
Care & Maintenance
Standard cleaning with mild soap and water if kept as a mineral specimen.
Interesting Facts
Many rough stones found outdoors are mistaken for diamonds due to sparkle from quartz cleavage planes, but lack the extreme hardness and refractive index of genuine diamond.
